Metamaterial characteristics- 6.7.24

Metamaterial- Wave propagation Negative permittivity and permeability  To enhance efficiency  It can be done using L and C F=1/2pie(root LC) No specific formula to vary the L and C in the design.But the optimization can be done by using optimetrics. Metamaterial has the ability to enhance efficiency and wave propagation in specific direction. Increase the bandwidth of the radiation in the antenna. Cost can be reduced by adding more sensitivity Use optimetrics to get required Frequency in HFSS 7/8/24 In DC We say it as Resistance  In AC W say it as Impedance  Transmission Lines: Waveguides  coaxial cable  Types of Antenna array :  Planar Antenna array  Circular Antenna array Linear Antenna array In Antenna to connect more antennas that is arrays antenna the power divider circuit is used. Why arrays Antenna? To increase the directivity  Directivity is proportionally to the gain.To increase the gain.... Impedance matching  Input impedance s...
